Why is the crust of ice-covered moon cakes hard?
In general, the main ingredients of mooncake skin are glutinous rice flour, sticky rice flour and cornstarch. Sticky rice flour is rice flour. Compared with glutinous rice flour, sticky rice flour is not sticky, which can avoid the taste of ice crust being too soft and waxy. Wheat starch, also known as clear noodles, not only makes the ice skin look more transparent, but also increases the toughness of the ice skin taste.
Where is the problem? In fact, the problem lies in glutinous rice flour! Why do homemade moon cakes with ice skin harden? How can I not harden? When starch is aged and gelatinized, the hot glutinous rice amylopectin will be gelatinized and easily decomposed by human digestive enzymes. After cooling, the amylopectin in glutinous rice may regrow just like amylose (it is generally believed that amylopectin is not easy to regrow, but it may still do so when the degree of polymerization of short branches outside amylopectin reaches 15- 18), so it is not easily digested by digestive enzymes. Therefore, when the glutinous rice is cold, it will become hard, sticky and chewy, which will affect digestion.

Just look at the overall formula, add other powders, delay the adjustment so that glutinous rice flour is not so easy to harden, and reduce the degree of hardening of glutinous rice flour.
